Notion got there first, launching in 2013 — that's 6 years of extra runway. Glean didn't arrive until 2019. In AI, that kind of head start means more training data, deeper customer relationships, and a bigger talent moat.

Glean has about 500 employees; Notion has about 2500. A bigger team usually means more revenue or heavier VC backing, but in AI, small teams can build at massive scale.
